基于远程学习者模型的差异化教学目标设计     

武法提  李彤彤 《现代远程教育研究》2013,(3):66-71

我国远程开放教育生源复杂,对远程学习者进行分类培养是远程教育的现实需求。然而,当前远程教育教学大都对所有学习者提供完全相同的目标和条件支持,忽略了学习者特征和需求的差异,不利于因材施教及提升远程教育效果。如何为充满差异的远程学习者提供符合学习者特征的、促进学生个性化发展的差异化教学是当前远程开放教育领域的重要研究课题。教学目标对教学过程起着导向作用,其分析与设计是教学工作的起点,差异化的教学目标设计是远程开放教育实施差异化教学的首要工作。教学目标的差异化维度包括目标起点、目标终点、目标容量以及目标程度四个维度;远程学习者的初始水平、学习投入、学习能力是影响教学目标差异化的关键特征。在进行差异化教学目标设计过程中,首先要对教学目标进行精细化分析,然后基于学习者关键特征收集学习者信息,最后在完成二者的基础上,通过设定最低目标以及建立学习者特征与差异化教学目标对应关系的方法来生成差异化的教学目标。  相似文献   

Immunomodulative effects of mesenchymal stem cells derived from human embryonic stem cells in vivo and in vitro     

Tan Z  Su ZY  Wu RR  Gu B  Liu YK  Zhao XL  Zhang M 《Journal of Zhejiang University. Science. B》2011,12(1):18-27

Objective  

Human embryonic stem cells (hESCs) have recently been reported as an unlimited source of mesenchymal stem cells (MSCs). The present study not only provides an identical and clinically compliant MSC source derived from hESCs (hESC-MSCs), but also describes the immunomodulative effects of hESC-MSCs in vitro and in vivo for a carbon tetrachloride (CCl₄)-induced liver inflammation model.  相似文献   

Assessing individualized instruction in the classroom: Comparing teacher,student, and observer perspectives     

《Learning and Instruction》2022

In this article, we address the measurement of individualized instruction in the context of regular classroom instruction. Our study assessed instructional practices geared towards individualization in German third grade reading lessons by combining self-report data from 621 students, from their teachers (n = 57), and live observations. We then investigated the reliability of these different approaches to measuring individualization as well as the agreement between them. All three approaches yielded reliable indicators of individualized practices, but not all of them corresponded with each other. We found considerable agreement between students and observers, but neither agreed with teachers' self-reports. Upon closer examination, we found that students’ ratings only correlated with teacher ratings that were provided close to the timepoint of interest. This correlation increased when teacher measures were corrected for response tendencies. We conclude with some recommendations for future studies that aim to measure individualized instruction in the classroom.  相似文献

枞阳县东部地区方言声母的普通话辨正——声母Ф、η、n与1     

谢翠萍 《池州师专学报》2012,(4):67-69

枞阳县东部地区方言零声母包括普通话里的部分零声母、r声母和个别l声母;方言η声母是普通话的部分零声母;声母n、l在方言里有混淆不分的现象,但有些音节则区分得很清楚。本文主要就方言声母Ф、η、n和l与普通话相对应的声母进行比较,阐明方音辨正的方法。  相似文献
